The band members told Fallon about speaking in front of the United Nations, the best things they experienced in New York City and what they want to accomplish in the future, including going to the Grammy awards.

"I was like so nervous," RM said about the U.N. speech to promote their "Love Yourself" message. "I was holding up the paper and you could see my hands shaking."

On Good Morning America on Wednesday, the band was surrounded by screaming fans as they took to the dance floor for "Idol" in a high-energy, highly-choreographed performance.

The band resumes their tour on Friday in Newark, N.J., in support of their most recent album, Love Yourself: Answer.
